Irisone Chemical Properties,Usage,Production

Description

β-Ionone has a characteristic violet-like odor, more fruity and woody than α-ionone. May be prepared by condensing citral with acetone to form pseudoionone, which is then cyclized by acid-type reagents.

Chemical Properties

β-Ionone has a characteristic violet-like odor, more fruity and woody than α-ionone

Chemical Properties

clear slightly yellow to yellow liquid

Occurrence

Reported found in the distillate from flowers of Boronia megatisma Nees. Also reported found in apricot, orange juice, lemon peel oil, guava, grapes, melon, papaya, peach, raspberry, blackberry, carrot, peas, bell pepper, tomato, ginger, peppermint and spearmint oil, milk powder, beef, hop oil, cognac, whiskies, grape wines, tea, passion fruit, plum, beans, mushroom, starfruit, almonds, mango, fenugreek, tamarind, apple and pear brandy, rice bran, quince, prickly pear, sweet potato, buckwheat, corn oil, corn tortillas, loquat, mountain papaya, clary sage and other sources

Uses

beta-Lonone is an essential oil extract from the leaves and flowers of Succisa Pratensis that shows antioxidant and antimicrobial activities against bacteria.

Uses

β-Ionone may be used as a reference standard in the determination of β-ionone in wine using solid-phase extraction followed by gas chromatography with mass spectrometry (GC-MS).

Definition

ChEBI: Beta-ionone is an ionone that is but-3-en-2-one substituted by a 2,6,6-trimethylcyclohex-1-en-1-yl group at position 4. It has a role as an antioxidant and a fragrance.

Preparation

By condensing citral with acetone to form pseudoionone, which is then cyclized by acid-type reagents.

Aroma threshold values

Detection: 0.007 to 205 ppb

Taste threshold values

Taste characteristics art 10 ppm: woody, sweet, fruity, berry-like with a green berry background

General Description

Colorless to light yellow liquid with an odor of cedar wood. In very dilute alcoholic solution the odor resembles odor of violets. Used in perfumery.

Air & Water Reactions

Slightly water soluble .

Reactivity Profile

Irisone may react vigorously with oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.
